<p>通过这个步骤就可以实现每一个图表组件切换主题了.不过有一些原生 HTML 中的样式需要调整</p>
</li>
</ul>
<h2 id="原生-HTML-主题样式适配"><a href="#原生-HTML-主题样式适配" class="headerlink" title="原生 HTML 主题样式适配"></a>原生 HTML 主题样式适配</h2><ul>
<li><p>创建 <code>utils/theme_utils.js</code> 文件</p>
<p>定义两个主题下, 需要进行样式切换的样式数据, 并对外导出一个函数, 用于方便的通过主题名称得 到对应主题的某些配置项</p>
